Microsoft Local Troubleshooter ActiveX Control Buffer Overflow (Technical
Details)
------------------------------------------------------------------------
SUMMARY
Microsoft Local Troubleshooter is an ActiveX control that is not very well
documented, it is usually used by Microsoft Windows's trouble shooting
help. This control is installed by default under the Windows 2000
operating systems. When one of its methods is called with a long string a
buffer overflow occurs, this overflow can be used by attacker to cause it
to execute arbitrary code.
DETAILS
This ActiveX control has a few methods and properties. One of the methods
called "RunQuery2" has a buffer overflow when it is called with a long
string in first parameter.
To reproduce the overflow just copy-and-paste the following:
------sample.htm-----------
< object id="test" classid="CLSID:4B106874-DD36-11D0-8B44-00A024DD9EFF">
</object>
< script> test.RunQuery2("longstringhere","","");
</script>
---------------------------
Microsoft Local Troubleshooter ActiveX control is marked as safe for
scripting and initialization, so the above sample will run without being
blocked (in default Internet Explorer security configuration).
This vulnerability can be exploited through XSS, sending to a victim an
HTML e-mail, or social engineering a user to open an HTML page specially
constructed. Exploitation of this vulnerability could allow an attacker to
execute code of his choice in the victim computer.
Vendor Status:
Microsoft released a fix.
